Perhaps you should try some spelling variations:
xiaodong hong » xiaodong huang, xiaotong zhang
ren xiaodong » lin xiaodong, wang xiaodong, du xiaodong
cheng ming » cheng bing, cheng ling, zhang ming
chen ping » chen rong, chen wang
chen yang » chen rong
ke zhang » ceo zhang, jie zhang, _ zhang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ren xiaodong hong ((((chen ping) OR (chen yang))) OR (cheng ming)) fang ke zhang (hai OR hadi) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ren xiaodong hong ((((chen ping) OR (chen yang))) or (cheng ming)) fang ke zhang (hai or hadi) ;~".
• Adding a wildcard symbol may retrieve word variants: ren xiaodong hong ((((chen ping) OR (chen yang))) or (cheng ming)) fang ke zhang (hai or hadi) ;*.
